Petunia plant named ‘Wespecapink’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Wespecapink’, characterized by its cascading, roughly spherical growth habit; freely branching plant habit; freely flowering habit; finely textured foliage; and single pastel pink colored flowers with purple colored venation.

Botanical classification/cultivar designation: Petunia×hybrida cultivar Wespecapink.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the name ‘Wespecapink’.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Südlohn-Oeding, Germany. The new Petunia originated from a cross-pollination made by the Inventor of a proprietary Petunia seedling selection identified as code number 98K8463-332, not patented, as the female, or seed, parent with a proprietary Petunia seedling selection identified as code number 98K66384-562, not patented, as the male, or pollen, parent. The new Petunia was selected by the Inventor in 2000 in a controlled environment in Südlohn-Oeding, Germany.

Asexual reproduction of the new cultivar by terminal cuttings taken in Südlohn-Oeding, Germany since 2001, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Wespecapink have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Wespecapink’. These characteristics in combination distinguish ‘Wespecapink’ as a new and distinct Petunia cultivar:

1. Cascading and roughly spherical growth habit.

2. Freely branching plant habit.

3. Freely flowering habit.

4. Finely textured foliage.

5. Single pastel pink-colored flowers with purple-colored venation.

Plants of the new Petunia are more trailing, more freely branching and have larger flowers than plants of the female parent. Plants of the new Petunia produce flowers that are larger, open fully and are of a different color than plants of the male parent.

Plants of the cultivar Wespecapink can be compared to plants of the Petunia cultivar Wespemab, disclosed in U.S. Plant Pat. No. 14,165. However in side-by-side comparisons conducted in Südlohn-Oeding, Germany, plants of the new Petunia and the cultivar Wespemab, differed in the following characteristics:

1. Plants of the new Petunia were shorter than plants of the cultivar Wespemab.

2. Plants of the new Petunia had smaller leaves than plants of the cultivar Wespemab.

3. Flowers of the new Petunia were larger than flowers of the cultivar Wespemab.

4. Plants of the new Petunia had shorter sepals and longer peduncles than plants of the cultivar Wespemab.

5. Flower color of the new Petunia is different from flower color of the cultivar Wespemab.

Plants of the cultivar Wespecapink can also be compared to plants of the Petunia cultivar Wespesoro, disclosed in U.S. Plant Pat. No. 14,184. However, in side-by-side comparisons conducted in Südlohn-Oeding, Germany, plants of the new Petunia and the cultivar Wespesoro differed in the following characteristics:

1. Plants of the new Petunia had smaller leaves than plants of the cultivar Wespesoro.

2. Plants of the new Petunia had smaller sepals and shorter peduncles than plants of the cultivar Wespesoro.

3. Flowers of the new Petunia were smaller than flowers of the cultivar Wespesoro.

4. Flowers of the new Petunia had a different color than flowers of the cultivar Wespesoro.

5. Anther color of flowers of the new Petunia differed from anther color of flowers of the cultivar Wespesoro.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photographs and the following botanical description were grown in 12-cm containers during the spring and summer for about 20 weeks in a glass-covered greenhouse and under conditions that closely approximate commercial production conditions in Südlohn-Oeding, Germany. During the production of the plants, day temperatures were about 20 to 25° C., night temperatures were about 16 to 18° C. and light levels ranged from 3,000 to 50,000 lux.
